Despite the wad replacing Thy Flesh Consumed, its level title graphics and intermission screen background replace those of the first episode, Knee-Deep in the Dead. This is a workaround for a bug in Doom95, one of the two source ports with which this wad was tested (the other being ZDoom 1.17)[1], in which the game would incorrectly display the first episode's intermission screen instead of the fourth's. The wad also uses blank graphics for Knee-Deep in the Dead's intermission animations to disguise this. As a result, Crusades' intermission will display incorrectly in any source port other than Doom95.
